Hi there, congratulations on your pregnancy! I will be completely honest about my experience, I've been taking 20mg a day for 10 years.
2 doctors and a specialist advised me to stay on my medication during pregnancy as a happy mummy was best and there was a worry coming off the meds would send me into relapse.
At no point was I told about any effects on baby. My baby girl was born at 36 weeks due to pre eclampsia (unrelated), and we noticed within hours that she was very shaky and jittery. She was also very drowsy and would visibly shake in her sleep and would throw her arms and legs out. I was very scared and ended up in tears thinking it was neurological as nobody had warned me at any point it could be the citalopram.
A peadetrician was called to examine her and she was diagnosed with withdrawal. Treatment was swaddling her and giving her a dummy to calm her, this helped. They advised the jitters would stop in 3-4 days and this was true, in a week she was like w different baby.
However I was terrified and wish someone had warned me about the effect on baby, I had no idea but after doing my own research it was clear that she had it. And that was on a relatively low dose.
Looking back, I think if I knew the effect on baby I'd have stayed on the dose, as she was completely fine in a week and it meant I was happy and healthy in pregnancy. But I really wished I had been warned, as at the time I was terrified something was wrong with my baby then was wracked with guilt my medication had done that to her.
However in the end it was all very short lived, and now she is absolutely fine.
